Java Definition


is an object-oriented programming language created by employees from Sun Microsystems (now Oracle). Its emblem is a cup of steaming coffee and it would come from the fact that “java” means coffee in American slang which is the inescapable developers’ beverage.


There are many frameworks, platforms and APIs that make Java portable on different operating systems. Among the 4 major frameworks, the “Java 2 Platform, Enterprise Edition”, abbreviated as “J2EE”, is the one specialized in server applications. Today, this name has disappeared, to give way to Java EE.

Java EE

However, on the web, we still meet the different names J2EE, JEE or Java EE. But, if we refer to the rules laid down by Oracle, we should now only say “Java EE” and forget the first two names.
For more details, see the Java Naming page on the Oracle website.

Java Developer : Missions

Java Developer,
in general, is not very different from C ++ developer, or developer in any computer language. It consists first in understanding a need, being able to specify it in actions or behaviors, and giving it a form, even if it is virtual.
For Marius, Java engineer at AViSTO, « it is above all a process of creation and the Java language is the tool that allows its realization. »
